GEORGE MILLER WEST, OF LOS ANGELES, CALIFORNIA.

GANG-PLOW.

To all whom it may concern:

Be it known that I, GEORGE MILLER \Vns'r, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented certain new and useful Improvements inGang- Plows, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates to new and useful improvements in plows and moreparticularly to a gang low, having for its object to provide a device ofthis character which is adjustable and is provided with extension meansthereon.

A further object of the invention resides in providing a frame having aplurality of plow beams thereon, which beams are adjustable, and a stillfurther object resides in providing extensions for the frame, whichextensions are also provided with plow beams and plows thereon.

' A further object of the invention resides in disposing this framecarrying the plow beams at an angle to the main frame of the device, anda still further object resides in providing means for the raising andlowering of the extensions and the raising and lowering of the completeframe.

Still another object resides in providing a device which is simple anddurable in construction, and very eflicient in operation.

WVith these and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawings forming a part of this application, Figure1 is a top plan View of the device. Fig. 2 is a side elevation thereof.Fig. 3 is a rear elevation of the same showing the extensions in theirraised positions, Fig. 4 is a side elevation of the cultivatinginstrument which may be substituted for the plows on the device shown inthe foregoing figures, and Fig. 5 is a detail perspective view of thesections of the hinge member used to secure the extensions to theadditional frame.

In carrying out my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which- 1 indicates a main frame designed pref-Specification of Letters Patent.

erably rectangular, as is usual in such agricultural implements, saidframe having ex tending transversely thereacross, the shaft or axle 2,upon the ends of which are rotatably mounted the supporting wheels 3,and extending from the frame 1, the usual draft tongue 4, while a seat 5is also mounted on the frame, whereby an operator may be seated thereonand the device driven forwardly. crumed to the side bars of the frame 1,respectively, adjacent the front and rear bars thereof, have the lowerends thereof pivotally engaged with a frame 8 designed to form asubstantial parallelogram, the front and rear bars of which are paralleland dis posed on the bias with respect to the frame 1 so as to extendfrom one corner to the opposite corner thereof. This frame 8 is disposedpa 'allel to the frame 1 and it may be said to have its transverse axisextended at an angle to that of said frame 1, and extendinglongitudinally of said frame 8 and connecting the front and rear barsthereof, are a plurality of bars or what may be termed plow beams 9.These bars 9 are arranged at regular intervals throughout the length ofthe frame 9 and are removable thereon, the ends of the same being heldto the front and rear bars of the frame by means of the bolts and nuts10 and 11, respectively. Each of these bars 9 has secured thereto, akeeper 1? through which extends the shank of a plow 13, and from thisconstruction, it will be seen that the device may be driven forwardly toallow the ground to be plowed in rows, and it will also be appreciatedthat in view of the fact that these bars 9 carrying the plows, areremovable or adjustable, any number of the same may be removed toincrease the distance between the rows when desired. As this frame 8 iscarried on the ends of the lovers '6 and 7, it will also be seen thatwhen it is desired to raise said frame so that the plows thereon will bedisengaged from the ground as the device is propelled, said levers maybe shifted in the required direction to accomplish this result, andfurther, in order to retain the levers in the adjusted position, thesegmental 'acks 14 are provided adjacent said levers 6 and 7, whichracks are adapted to be engaged by the detents or the like 15 carried onthe lovers. These detents are also adapted to be engaged with the teethof the racks when the frame is lowered A pair of levers 6 and 7 fill inits effective position so as to cause the same to remain in thisposition throughout the operation of the device.

The end bars of the frame 8 are disposed in alinement with and below theside bars of the frame 1, so that the ground over which this device ispropelled, will not be plowed beyond the supporting wheels thereon, butI have also provided means whereby a greater area of ground can beplowed when desired, and to this extent, I provide the extensions 16 and17 on the frame 8. These extensions merely continue the parallelogramformed by the frame 8, the same being hinged to the end bars thereof bymeans of the hinges l8, and each of said extensions is provided with aplurality of longitudinal plow beams or bars carrying plows, aspreviously mentioned in the description of the frame 8. In order thatthese extensions 16 and 17 may be raised or lowered when desired, thelevers 19 and 20 are provided, which are fulcrumed on the main frame 1and have their lower ends, respectively, connected with the inner endsof the rods 19 and 20, the outer ends of said rods being pivotallyconnected to the extensions 16 and 17, respectively, whereby when saidlevers are moved inwardly toward the longitudinal center of the mainframe 1, said extensions will be raised, and when moved in the oppositedirection, said extensions will be lowered. In order to retain thelevers 19 and 20 in any adjusted position, the segmental racks 21 areprovided in connection therewith, the teeth of which are adapted to beengaged by the detents 22 on the levers, and thus, said extensions maybe held in their effective or ineffective positions. I have alsoprovided means for the regulation of the depth of ground entered by theplows as the device is propelled, and to this extent, the colters 23 areprovided, which colters are carried on the ends of the arms 24: whichare, in turn, adjustably mounted on the sides of the extensions 16 and17. It must here also be stated that while I have particularly describedthis device as being a gang plow, the plows 13 which are carried on thebeams 9, are removably mounted thereon and may be interchanged for anydesired ground-treating implement, whatsoever, and in order to show theuse of this device as a cultivator, I have shown in Fig. 4 a particulargroundtreating implement or shovel 25. Instead of the plows being used,these shovels 25 may be substituted therefor, and the device may be usedas a cultivator for a plurality of rows on the field. In thisconnection, I will also state that the device is capable of variouschanges in form, proportion and in the minor details of constructionwithout departing from the spirit or sacrificing any of the principlesof the invention.

From the foregoing, it will be seen that I have provided an improvedgang plow wherein any number of plows may be provided for plowing afield in rows, and it will further be seen that in view of theadjustability of the plow beams, the space be tween the rows may beregulated, as desired. Furthermore, it will be seen that I have providedmeans for the plowing of a greater area of ground than is provided bythe ordinary plow of this type, which means comprises the extensionsdescribed. It will still further be seen that I have provided means forthe regulation of these extensions, whereby the samemay be readily movedinto effective or ineffective position. It will still further be seenthat the device complete comprises comparatively few and simple parts,which parts are durable in construction and inexpensive to manufacture,and the device is one which is extremely eflicient and useful inoperation.

What I claim is 1. A plow of the class described comprising a main framesupported on wheels, an additional frame suspended therebelow andextending diagonally of said main frame, the extreme ends of saidadditional frame being respectively disposed forwardly and rearwardly ofthe front and rear bars of said main frame, extensions for saidadditional frame hingedly carried on the ends thereof, plows carried onsaid additional frame and the extensions thereof, and means at the frontand rear ends respectively of said main frame to raise and lower saidextensions.

2. A plow of the class described comprising a main frame, supportingwheels therefor, an additional frame movably suspended therebelow andextending diagonally of said main frame, the extreme ends of saidadditional frame extending respectively beyond the front and rear barsof said main frame, extensions for said additional frame hingedlyengaged with the ends thereof, plows removably secured to saidadditional frame and the extensions of the same, means on the side barsof said main frame at the front and rear ends respectively thereof forraising and lowering said additional frame, and means on the front andrear bars respec tively of said main frame for raising and lowering thehinged extensions of said additional frame.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
